Notes
Display Buttons
- ADJ = Top left button
- SET = Bottom left button
Clock Adjust
In the normal display mode, press and hold the “ADJ” button for 3 seconds to make the “minute” figure flash. Press the “ADJ” button briefly to increase the minutes by one. If you hold the “ADJ” button, the minutes will increase continuously until you release it. Once the minutes are adjusted, press the “SET” button briefly, and the “hour” figure will begin flashing. Press the “ADJ” button briefly to increase the hour by one. Holding the “ADJ” button will increase the hours continuously until released. After adjusting both the hour and minute, save the settings and exit.
Metric System Switching
In normal display mode, press and hold the “SET” button for 10 seconds to switch from “km/h” to “MPH.” Release the button, then press and hold the “SET” button for another 10 seconds to switch back from “MPH” to “km/h.”
Reset the TRIP
In normal display mode, press and hold the “SET” button for 3 seconds to reset the subtotal trip.
Display Speed Accuracy
A setting of 16.5 Hertz won’t provide a more accurate display reading, as it’s too broad. Accuracy with the current hardware can only be achieved within a specific subset of the bike’s total speed range, and at a constant velocity. Adjusting the bike’s Hertz reading will only shift that subset range of “increased” accuracy up or down the bike’s speed ranges. In other words, you need to choose whether you want more accuracy at higher, medium, or lower speeds. The Hertz setting determines where this accuracy range will be within the bike’s speed spectrum.
Out of the box, the display is programmed to provide generally accurate readings across the entire range of the bike’s speeds. You can think of it like the Doppler effect: imagine race cars on a track. As the cars approach, their sound waves are compressed, producing higher frequencies. Once they pass, the sound waves elongate, and the pitch lowers. You only hear the car exactly as it sounds when it is directly in front of you. Similarly, the display aims to give a good overall reading and enrich the riding experience.
To be more precise, determining velocity at a given moment is complex. It requires additional hardware, like encoders, which continuously measure points on moving parts, or triangulation methods such as GPS. Regardless of the exact accuracy, ride at a level you’re comfortable with, as that’s ultimately what matters.
Adjust the Speedometer Parameters
The following instructions are related to the speedometer section of the display interface and do not involve other segments of the LCD. The key referred to here is the SEL key. When the host computer is set to use MPH, the text file description can be modified to switch it to KPH. If you return without changing the speed or mileage corresponding to a 60 km/h frequency, the last set value will be retained. However, if you modify the speed or mileage to any value other than 60 km/h, the display will switch to the corresponding metric parameters.
- Display Password: 6610
Press and hold the key to power on the device and enter the password operation interface, where the LCD will display “P-0000” with a low 1Hz flash. In the password operation interface, briefly press the flashing digits to increment them by 1, with values ranging from 0 to 9 in a repeating cycle. To adjust the flashing digit, press and hold it to shift the value to the left. After setting all four digits, if the input matches the parameter setting password (6610), the system will directly enter the vehicle speed ratio set interface. If the input matches the Cumulative Clear Interface password (8810), it will clear the settings directly. If it matches the Cumulative Setting Interface password (6810), the system will enter the Cumulative Setting Interface. If none of these passwords match, the system will return to the password operation interface and display “P-0000.”
